Fri Dec 8 13:04:51 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu> cvs/libc-951210 cvs/libc-951209

	* locale/error.c, locale/error.h: Files removed.
	* locale/Makefile (distribute): Remove error.h.
	(lib-modules): Remove error.

	* hurd/hurdlookup.c (__hurd_file_name_lookup_retry): For "tty"
	magic, return ENXIO if no ctty.

	* sysdeps/mach/hurd/mmap.c: For MAP_FIXED, deallocate a previous
	mapping if vm_map fails for that reason.

	* posix/glob.c: Implement new options GLOB_ALTDIRFUNC, GLOB_BRACE,
	GLOB_TILDE, GLOB_NOMAGIC.
	(glob): Use stat instead of lstat to determine directoriness.
	* posix/glob.h (GLOB_ALTDIRFUNC, GLOB_BRACE, GLOB_NOMAGIC, GLOB_TILDE):
	New flag bits.
	(__GLOB_FLAGS): Include them.
	(glob_t): New members gl_closedir, gl_readdir, gl_opendir, gl_lstat,
	gl_stat.

	* elf/elf.h (ET_NUM, SHT_NUM, STB_NUM, STT_NUM, PT_NUM): New macros.

	* sysdeps/unix/sysv/linux/sys/mman.h: Include <linux/mman.h> to
	define all the bit values.
	(MAP_*, MCL_*): Macros removed.
